.\" The -*- nroff -*- definitions below are for supplemental macros used
.\" in Tcl/Tk manual entries.
.\"
.\" .AP type name in/out ?indent?
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",
.\"	or "in/out" to describe whether procedure reads or modifies arg,
.\"	and indent is equivalent to second arg of .IP (shouldn't ever be
.\"	needed;  use .AS below instead)
.\"
.\" .AS ?type? ?name?
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed
.\"	to .AP later.  If args are omitted, default tab stops are used.
.\"
.\" .BS
.\"	Start box enclosure.  From here until next .BE, everything will be
.\"	enclosed in one large box.
.\"
.\" .BE
.\"	End of box enclosure.
.\"
.\" .CS
.\"	Begin code excerpt.
.\"
.\" .CE
.\"	End code excerpt.
.\"
.\" .VS ?version? ?br?
.\"	Begin vertical sidebar, for use in marking newly-changed parts
.\"	of man pages.  The first argument is ignored and used for recording
.\"	the version when the .VS was added, so that the sidebars can be
.\"	found and removed when they reach a certain age.  If another argument
.\"	is present, then a line break is forced before starting the sidebar.
.\"
.\" .VE
.\"	End of vertical sidebar.
.\"
.\" .DS
.\"	Begin an indented unfilled display.
.\"
.\" .DE
.\"	End of indented unfilled display.
.\"
.\" .SO ?manpage?
.\"	Start of list of standard options for a Tk widget. The manpage
.\"	argument defines where to look up the standard options; if
.\"	omitted, defaults to "options". The options follow on successive
.\"	lines, in three columns separated by tabs.
.\"
.\" .SE
.\"	End of list of standard options for a Tk widget.
.\"
.\" .OP cmdName dbName dbClass
.\"	Start of description of a specific option.  cmdName gives the
.\"	option's name as specified in the class command, dbName gives
.\"	the option's name in the option database, and dbClass gives
.\"	the option's class in the option database.
.\"
.\" .UL arg1 arg2
.\"	Print arg1 underlined, then print arg2 normally.
.\"
.\" .QW arg1 ?arg2?
.\"	Print arg1 in quotes, then arg2 normally (for trailing punctuation).
.\"
.\" .PQ arg1 ?arg2?
.\"	Print an open parenthesis, arg1 in quotes, then arg2 normally
.\"	(for trailing punctuation) and then a closing parenthesis.

.SH DESCRIPTION
.PP
This module implements a web server, suitable for embedding in an
application\&. The server is object oriented, and contains all of the
fundamentals needed for a full service website\&.
.PP
.SH "MINIMAL EXAMPLE"
Starting a web service requires starting a class of type
\fBhttpd::server\fR, and providing that server with one or more URIs
to service, and \fBhttpd::reply\fR derived classes to generate them\&.
.CS


oo::class create ::reply\&.hello {
  method content {} {
    my puts "<HTML><HEAD><TITLE>IRM Dispatch Server</TITLE></HEAD><BODY>"
    my puts "<h1>Hello World!</h1>"
    my puts </BODY></HTML>
  }
}
::httpd::server create HTTPD port 8015 myaddr 127\&.0\&.0\&.1 doc_root ~/htdocs
HTTPD plugin dispatch httpd::server::dispatch
HTTPD uri add * /hello [list mixin reply\&.hello]

.CE
The bare module does have facilities to hose a files from a file system\&. Files that end in a \&.tml will be substituted in the style of Tclhttpd:
.CS


<!-- hello\&.tml -->
[my html_header {Hello World!}]
Your Server is running\&.
<p>
The time is now [clock format [clock seconds]]
[my html_footer]

.CE
A complete example of an httpd server is in the /examples directory of Tcllib\&. It also show how to dispatch URIs to other processes via SCGI and HTTP proxies\&.

Converts a block of mime encoded text to a key/value list\&. If an exception is encountered,
the method will generate its own call to the \fBerror\fR method, and immediately invoke
the \fBoutput\fR method to produce an error code and close the connection\&.

.PP
.SS "CLASS  HTTPD::REPLY"
\fIancestors\fR: \fBhttpd::mime\fR
.PP
A class which shephards a request through the process of generating a
reply\&.
The socket associated with the reply is available at all times as the \fIchan\fR
variable\&.
The process of generating a reply begins with an \fBhttpd::server\fR generating a
\fBhttp::class\fR object, mixing in a set of behaviors and then invoking the reply
object's \fBdispatch\fR method\&.
In normal operations the \fBdispatch\fR method:
.IP [1]
Invokes the \fBreset\fR method for the object to populate default headers\&.
.IP [2]
Invokes the \fBHttpHeaders\fR method to stream the MIME headers out of the socket
.IP [3]
Invokes the \fBrequest parse\fR method to convert the stream of MIME headers into a
dict that can be read via the \fBrequest\fR method\&.
.IP [4]
Stores the raw stream of MIME headers in the \fIrawrequest\fR variable of the object\&.
.IP [5]
Invokes the \fBcontent\fR method for the object, generating an call to the \fBerror\fR
method if an exception is raised\&.
.IP [6]
Invokes the \fBoutput\fR method for the object
.PP
.PP
Developers have the option of streaming output to a buffer via the \fBputs\fR method of the
reply, or simply populating the \fIreply_body\fR variable of the object\&.
The information returned by the \fBcontent\fR method is not interpreted in any way\&.
If an exception is thrown (via the \fBerror\fR command in Tcl, for example) the caller will
auto-generate a 500 {Internal Error} message\&.
A typical implementation of \fBcontent\fR look like:
.CS



 clay::define ::test::content\&.file {
 	superclass ::httpd::content\&.file
 	# Return a file
 	# Note: this is using the content\&.file mixin which looks for the reply_file variable
 	# and will auto-compute the Content-Type
 	method content {} {
 	  my reset
     set doc_root [my request get DOCUMENT_ROOT]
     my variable reply_file
     set reply_file [file join $doc_root index\&.html]
 	}
 }
 clay::define ::test::content\&.time {
   # return the current system time
 	method content {} {
 		my variable reply_body
     my reply set Content-Type text/plain
 		set reply_body [clock seconds]
 	}
 }
 clay::define ::test::content\&.echo {
 	method content {} {
 		my variable reply_body
     my reply set Content-Type [my request get CONTENT_TYPE]
 		set reply_body [my PostData [my request get CONTENT_LENGTH]]
 	}
 }
 clay::define ::test::content\&.form_handler {
 	method content {} {
 	  set form [my FormData]
 	  my reply set Content-Type {text/html; charset=UTF-8}
     my puts [my html_header {My Dynamic Page}]
     my puts "<BODY>"
     my puts "You Sent<p>"
     my puts "<TABLE>"
     foreach {f v} $form {
       my puts "<TR><TH>$f</TH><TD><verbatim>$v</verbatim></TD>"
     }
     my puts "</TABLE><p>"
     my puts "Send some info:<p>"
     my puts "<FORM action=/[my request get REQUEST_PATH] method POST>"
     my puts "<TABLE>"
     foreach field {name rank serial_number} {
       set line "<TR><TH>$field</TH><TD><input name=\\"$field\\" "
       if {[dict exists $form $field]} {
         append line " value=\\"[dict get $form $field]\\"""
       }
       append line " /></TD></TR>"
       my puts $line
     }

.TP
method \fBreset\fR
Clear the contents of the \fIreply_body\fR variable, and reset all headers in the \fBreply\fR
structure back to the defaults for this object\&.
.TP
method \fBtimeOutCheck\fR
Called from the \fBhttp::server\fR object which spawned this reply\&. Checks to see
if too much time has elapsed while waiting for data or generating a reply, and issues
a timeout error to the request if it has, as well as destroy the object and close the
\fIchan\fR socket\&.
.TP
method \fBtimestamp\fR
Return the current system time in the format:
.CS

.TP
method \fBdestructor\fR ?\fIdictargs\fR?
.TP
method \fBconnect\fR \fIsock\fR \fIip\fR \fIport\fR
Reply to an open socket\&. This method builds a coroutine to manage the remainder
of the connection\&. The coroutine's operations are driven by the \fBConnect\fR method\&.
.TP
method \fBServerHeaders\fR \fIip\fR \fIhttp_request\fR \fImimetxt\fR
.TP
method \fBConnect\fR \fIuuid\fR \fIsock\fR \fIip\fR
This method reads HTTP headers, and then consults the \fBdispatch\fR method to
determine if the request is valid, and/or what kind of reply to generate\&. Under
normal cases, an object of class \fB::http::reply\fR is created, and that class's
\fBdispatch\fR method\&.
This action passes control of the socket to
the reply object\&. The reply object manages the rest of the transaction, including
closing the socket\&.
.TP
method \fBcounter\fR \fIwhich\fR
Increment an internal counter\&.
.TP
method \fBCheckTimeout\fR
Check open connections for a time out event\&.
.TP
method \fBdebug\fR ?\fIargs\fR?
.TP
method \fBdispatch\fR \fIdata\fR
Given a key/value list of information, return a data structure describing how
the server should reply\&.
.TP
method \fBDispatch_Default\fR \fIreply\fR
Method dispatch method of last resort before returning a 404 NOT FOUND error\&.
The default behavior is to look for a file in \fIDOCUMENT_ROOT\fR which
matches the query\&.
.TP
method \fBDispatch_Local\fR \fIdata\fR
Method dispatch method invoked prior to invoking methods implemented by plugins\&.
If this method returns a non-empty dictionary, that structure will be passed to
the reply\&. The default is an empty implementation\&.
.TP
method \fBHeaders_Local\fR \fIvarname\fR
Introspect and possibly modify a data structure destined for a reply\&. This
method is invoked before invoking Header methods implemented by plugins\&.
The default implementation is empty\&.
.TP
method \fBHeaders_Process\fR \fIvarname\fR
Introspect and possibly modify a data structure destined for a reply\&. This
method is built dynamically by the \fBplugin\fR method\&.
.TP
method \fBHostName\fR \fIipaddr\fR
Convert an ip address to a host name\&. If the server/ reverse_dns flag
is false, this method simply returns the IP address back\&.
Internally, this method uses the \fIdns\fR module from tcllib\&.
.TP
method \fBlog\fR ?\fIargs\fR?
Log an event\&. The input for args is free form\&. This method is intended
to be replaced by the user, and is a noop for a stock http::server object\&.
.TP
method \fBplugin\fR \fIslot\fR ?\fIclass\fR \fB\fR?
Incorporate behaviors from a plugin\&.
This method dynamically rebuilds the \fBDispatch\fR and \fBHeaders\fR
method\&. For every plugin, the server looks for the following entries in
\fIclay plugin/\fR:
.sp
\fIload\fR - A script to invoke in the server's namespace during the \fBplugin\fR method invokation\&.
.sp
\fIdispatch\fR - A script to stitch into the server's \fBDispatch\fR method\&.
.sp
\fIheaders\fR - A script to stitch into the server's \fBHeaders\fR method\&.
.sp
\fIthread\fR - A script to stitch into the server's \fBThread_start\fR method\&.
.TP
method \fBport_listening\fR
Return the actual port that httpd is listening on\&.
.TP
method \fBPrefixNormalize\fR \fIprefix\fR
For the stock version, trim trailing /'s and *'s from a prefix\&. This
method can be replaced by the end user to perform any other transformations
needed for the application\&.
.TP
method \fBsource\fR \fIfilename\fR
.TP
method \fBstart\fR
Open the socket listener\&.
.TP
method \fBstop\fR
Shut off the socket listener, and destroy any pending replies\&.
.TP
method \fBSubObject {} db\fR
.TP
method \fBSubObject {} default\fR
.TP
method \fBtemplate\fR \fIpage\fR
Return a template for the string \fIpage\fR
.TP
method \fBTemplateSearch\fR \fIpage\fR
Perform a search for the template that best matches \fIpage\fR\&. This
can include local file searches, in-memory structures, or even
database lookups\&. The stock implementation simply looks for files
with a \&.tml or \&.html extension in the ?doc_root? directory\&.
.TP
method \fBThread_start\fR
Built by the \fBplugin\fR method\&. Called by the \fBstart\fR method\&. Intended
to allow plugins to spawn worker threads\&.
.TP
method \fBUuid_Generate\fR
Generate a GUUID\&. Used to ensure every request has a unique ID\&.
The default implementation is:
.CS


   return [::clay::uuid generate]

.CE
.TP
method \fBValidate_Connection\fR \fIsock\fR \fIip\fR
Given a socket and an ip address, return true if this connection should
be terminated, or false if it should be allowed to continue\&. The stock
implementation always returns 0\&. This is intended for applications to
be able to implement black lists and/or provide security based on IP
address\&.
